For us, Quinta de Saude was the ideal holiday home - beautifully situated, well maintained and with a pool area that the kids (and the adults) absolutely loved. The rooms are very generous, and the living spaces cosy, while there are three separate areas for outside eating which is great for catching the sun at whatever time of day.
Location-wise, it was perfect for us - very quiet and away from it all - 20 minutes' drive to the beach at Foz Do Arelho and the beautiful town of Obidos. The nearest big supermarket is 10 mins away by car, which is about the same distance to the nearest restaurants.
Victoria and Antonio were there to greet us and were on hand to help with a couple of questions we had, which was very useful. They also provided a welcome hamper, which was most thoughtful.
The only thing that we were slightly disappointed with were some aspects of the kitchen. We found that there were certain things that we couldn't find (for example, a peeler, a sieve, smaller pans, baking/roasting trays) which made us improvise a little bit. The other thing was that there were no basics in the kitchen - salt, pepper, oil, etc - which are, in properties we've stayed in the past, usually there when you arrive. These are really minor quibbles though.
I can't recommend this place enough if you want a relaxing, beautiful holiday away from it all.
